` spcification or Letters Patent No. dated May e, 1844.

To all Lc/tom 'it concern Be it known that I, A. DQCriiLDs, of

Rochester, in the county of Monroe and State of New York, have invented a new and luseful Improvement in Horse-Powers; and I do hereby declare that the fololwing is a full, clear, and exact description thereof, reference being had tothe accompanying drawings, which forni a part `of this specification, in which- Figure l, is a 'perspective view. Fig. 2, is a top planwith the revolving cap removed and sho-wing the gearing; Fig. 3, a vertical section.

rIhe construction is` as follows: On a square timber frame (c) formed of four pieces which serve as sills, is bolted a cir-` cular ring (Zi), by arflanch that may project out at right angles from it at its lower edge, as shown in the drawing, or inn ward toward the center; this ring rises perpendicular a few inches, above which there is an olfset, enlarging the ring thellength of a cog, which is used the gearing, when it again rises; as clearly shown at (b) Fig. 3; the height of the cog above named, where it terminates in a horizontal outward lanch (52); the recess has teeth or cogs (d) projecting inward in it, the` face of said cogs being flush with the inner surface of the lower, and smaller part of the ring, these cogs form an internal stationary gear, and are cast with the ring, to the lower part of which is also` cast four arms (two of which are shown in Fig. 3 (6)) that join at the center and there support the lower end of a center shaft. i

Upon the stationary ring as above described a revolving cap turns; it consists of a flat circular plate (f) from` the center of which a short hollow truncated cone rises; this plate is of a diameter large enough to extend beyond the top tlanch (b2) of the lower ring; from t-he periphery of the plate are three equidistant segmental projections (f2) that are level with the horizontal surface of .said plate and having a square or conical shaped staple (f3) stand-` ing up on each to receive a radial lever, the inner end of which enters a hole in the truncated cone at the center; under the `staples a hole is made through the plateso Ithat in casting the mold forms its own cores, an advantage well known to practical founders; on the plate between the projections (f2) are semicircular hollow pieces (f4)` 4 the pinions l) jutting upward 4directly over the i lianch (62); in these areV put friction rollers (g) (see Fig. 3) on which the weightof the cap and its attachments rest; a Hauch (f5) extends downward from the plate and seg- Ament projections at their outer edge, and i this flanch supports a stud on which a friction roller turns at the point just under the roller (g) below the flanch (b2), by this arrangement the cap can beturned around without rising up. At the center of the segment projections are studs (i) fixed into the plate (f) which stand out on the under side far enough for axles for the planet wheels (7c, 7c, 76,) andtheir pinions (Z) which are joinedto their centers underneath them; workinto and are turned by the stationary gear around the inside of the ring (b) and bytheir attachment to the planet wheels above named cause them also to turn; the wheels extend inward to a .pinion (m) at the center on an upright shaft j (n) which turns on a pivotat its lower end in a step where the arms (e) before described meet; the upper end of the shaft is supported by a collar in the truncated cone at the center of cap (f) near the lower bearing of the shaft, a bevel wheel (o) is attached that gears into a bevel pinion (p) on a line shaft The wheels are held in their places by means of rollers (r), on the studs (i) which form a part of the cap, below or above the pinions, and bearing against a smooth part of the ring (b), guidethe pitch of the gearing and make it run steady by keeping the cap accurately in place. Between the wheels (7c), on the line between their centers, bosses i project down from the cap; and braces, which extend from one stud to another are bolted thereto; the braces being fort-he purpose of steadying the studs are connected with their lower ends. Instead of the braces above named a flat `plate may extend inward from the lanch (f5) under the planet wheel which answers the same purpose. The construction and guidance of the above parts form an essential feature in my machine and are important to its perfect operation.

icc

The line shaft (g) has a clutch box couf plingso that when the machine is driven in the proper direction the shaftturns and if the driving power is suddenly stopped the machine that is driven will have freedom to run on till its momentum is checked.` A universal oint also of common construction lli) may be also advantageously added to the shaft.

To guide the pitch of the Wheels it Will be obvious that friction rollers can be put into the flanch and bear against the outside of the stationary ring instead of those above described and lettered (r) in drawing; this I deem substantially the same as the method shown in the drawing.

What I claim as my invention and desire to secure by'Letters Patent is The method of sustaining the upper end the cap as described; Which is guided by l5 rollers on the studs of the cap under the planet Wheels bearing and rolling on the inner periphery of the permanentring by means of which a stationary center is dispensed with and the Wheels are protected.
